Use of vitamin and mineral supplements does not improve measures of performance in people consuming adequate vitamin levels in their diets!

Vitamins and minerals are necessary for a broad range of essential chemical reactions in the body, including those involved in energy metabolism, cell growth and repair, protection from free radical damage, and nerve and muscle function. Inadequate intake of vitamins and minerals leading to a body or tissue deficiency will impair the athlete’s health and performance.

Athletes who restrict their total energy intake or lack dietary variety are at risk of an inadequate intake of vitamins and minerals.

There is no evidence that supplementation with vitamins and minerals enhance performance except in cases where a pre-existing deficiency exists. It’s a myth that vitamin supplementation will enhance your performance when no deficiency exists. Vitamins may be recommended for certain individuals, such as the elderly, vegans, and women of childbearing age or people in counties with little to no sunlight.
